سَنُرِيهِمۡ ءَايَٰتِنَا فِي ٱلۡأٓفَاقِ وَفِيٓ أَنفُسِهِمۡ حَتَّىٰ يَتَبَيَّنَ لَهُمۡ أَنَّهُ ٱلۡحَقُّۗ أَوَلَمۡ يَكۡفِ بِرَبِّكَ أَنَّهُۥ عَلَىٰ كُلِّ شَيۡءٖ شَهِيدٌ ٥٣
We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth.1 But is it not sufficient concerning your Lord that He is, over all things, a Witness?2
Translation: Saheeh International (English)
1 Or "that He (subḥānahu wa taʿālā) is the Truth."
2 See footnote of 4:79.
Each word's meaning and sound
I will show them My signs in the heavens and on earth. I will show them My signs within souls so that it will become clear to them without any doubt that this Qur’ān is the truth without any doubt. Is it not enough for these idolaters that the Qur’ān is true by Allah’s testimony that it is from Him? Who can be a greater witness than Allah? If they were seeking the truth they would have sufficed with the testimony of their Lord.
